The H-C-H bond angle in methane, CH4, is known to be approximately 109.5° due to the tetrahedral arrangement of the four hydrogen atoms around the central carbon atom. Therefore, it is reasonable to assume that the H-C-H bond angle in CH₄, which also contains a tetrahedral carbon atom, would be similar to that of methane.
